Potentially explosive environments
Using or installing this radio in an area with a potentially explosive atmosphere is prohibited.
Switch off the radio when in any area with a potentially explosive atmosphere and obey all signs and instructions.
Potentially explosive atmospheres include areas where you would normally be advised to turn off your vehicle
engine. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.
Switch off the radio near refueling points such as gas pumps at service stations.
Observe restrictions on the use of radio equipment in fuel depots, storage and distribution areas, chemical plants, or
where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include below-deck
on boats, chemical transfer or storage facilities, vehicles using liquefied petroleum gas (such as propane or butane),
and areas where the air contains chemicals or particles such as grain, dust, or metal powders.
Care and maintenance
The TW1m modem is a product of superior design and craftsmanship and should be treated with care. The
suggestions below will help you fulfil any warranty obligations and enjoy this product for many years.
• Keep the TW1m modem and all its parts and accessories out of reach of small children.
• Keep the TW1m modem dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that
will corrode electronic circuits.
• Do not use or store the TW1m modem in dusty, dirty areas. Its moving parts can be damaged.
• Do not store the TW1m modem in hot areas. High temperatures can shorten the life of electronic devices,
damage batteries and warp or melt certain plastics.
• Do not store the TW1m modem in cold areas. When it warms up (to its normal temperature), moisture can form
inside, which may damage electronic circuit boards.
• Do not drop, knock or shake the TW1m modem. Rough handling can break internal circuit boards.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the TW1m modem. Use only
detergents meant for electronic devices and printed circuit boards.
• Do not paint the TW1m modem. Paint can clog the moving parts and prevent proper operation.
• Use only the accessory antennas or other approved antennas. Unauthorised antennas, modifications or
attachments could damage the phone and may violate regulations governing radio devices.
All of the above suggestions apply equally to the product, charger or any accessory.
Note:
The Global Positioning System
The Global Positioning System (GPS) is operated by the United States government, which is solely
responsible for the accuracy and maintenance of the system. The accuracy of location data can be affected
by adjustments to GPS satellites made by the United States government and is subject to change with the
United States Department of Defense civil GPS policy and the Federal Radionavigation Plan. Accuracy can
also be affected by poor satellite geometry.
Availability and quality of GPS signals may be affected by buildings and natural obstacles as well as weather
conditions. The GPS receiver should only be used outdoors to allow reception of GPS signals. The GPS
should not therefore be used for precise location measurement and you should never rely solely on location
data from the GPS receiver.
